Ebenezer McCoy is Harry’s mentor. He’s a stocky man in overalls. He’s got a farm so I figured his overall’s aren’t completely clear and he’s probably got some sturdy work boots. He’s got some thick arms for farming work. I wanted to him to have an overall impression of sturdiness. He’s described as bald except for tuffs on the the side of his head and a beard. I also kept in mind a reveal later in the series of who he is related to. So I gave him a fairly sharp nose and little bit of a point to his eyebrows.
